Specific embodiment
As shown in Figure 1, shown in Figure 11, using ABB AB's AC800F system hardwares, S800 series I/O modules lead between controller
Ethernet connection is crossed, is connected by Profibus DP between controller and IO, connected by Modbus with 800 touch screens of panel
Connect, compatible various bus protocols.
ACC system major control object is charging plate washer and skewed slot, pusher, fire grate, First air plate washer, secondary wind shelves
Plate, mucking machine（Fig. 2）, hydraulic oil unit, hydraulic oil pump and hydraulic oil pipe shut-off valve（Fig. 3）.As shown in Fig. 2 rubbish is by charging
Plate washer, feed chute enter incinerator, by pusher, the migration of fire grate, provide combustion-supporting sky by First air, secondary wind
Gas, is burned in incinerator, and the slag for burning is cooled down by mucking machine, conveying.
As shown in Figure 4, Figure 5, in Refuse Incineration Process, it may occur that heat transfer process, and burning process input and
The heat of output should be that total amount is equal.And except the heat contained by rubbish, other caloric values can be transferred through actual measured value
Calculate, according to principle of heat balance, calculate the heat burnt away the refuse in a period of time.It is subsequently used for calculating given
Under the demand of quantity of steam, required quantity of refuse, so as to calculate the speed of required garbage feeding, and combustion-supporting air quantity,
Here it is ACC main function.
Garbage feeding baffle plate is located between feed hopper and feed chute, and effect is：1) when garbage feeding flapper closure, rubbish
Cannot propagate into feed chute；2) once the rubbish material position in skewed slot is too low, then need to close plate washer to keep inside incinerator
Negative pressure, prevent foul smell diffusion or the waste gas lighted in dump pit of flare and rubbish in incinerator, to ensure safety.
In normal operating, the garbage feeding baffle plate in feed chute is to open, but if in garbage feeding skewed slot
Rubbish material position is too low, and garbage feeding baffle plate is automatically switched off.In unit starting and stopped process, garbage feeding baffle plate must be closed
Close.
When there is following either case, garbage feeding baffle plate should perform out code：1) when the rubbish in feed chute
Position is as little as it is impossible to ensure that enough incinerator aeroseals；Or rubbish can not be fed on fire grate 2)；3) when boiler stops.
When situations below meets simultaneously, hang to rubbish and send the instruction that feeds intake：1) feed chute material position is low；2) feed plate washer leaf
Piece is opened.When feed chute return water temperature is too high, hangs to rubbish and send region danger signal.Region danger signal and blade with
Opening signal simultaneously in the presence of, hang to send to rubbish and forbid the instruction that feeds intake.
According to Fig. 6, rubbish enters incinerator by the impetus of 11 pushers.In order to allow incinerator according to setting
Constant load works, and calculates the speed setting value of pusher, while by the rubbish thickness effect on the fire grate of the second level, controlling pusher
The speed of device, and then control the junk traffic into incinerator.
11 pushers are divided into left and right two groups, are fed to arranged on left and right sides fire grate respectively.In order to ensure into incinerator stove
Rubbish on row can be evenly distributed relatively, it is desirable to the pusher unit synchronization action in each group pusher.
The action of pusher is divided into three phases：1) compression stroke, is moved forward with fixed speed at a high speed, before pusher
Rubbish will be compressed.2) feed stroke, pusher are moved forward compared with low velocity with controllable, by rubbish from feed chute
Shift onto on the first order fire grate lower section.3）Backward stroke, is returned with fixed speed at a high speed in this stage pusher.The system is only controlled
Speed of the pusher processed in feed stroke, other stages are with fixed speed action.
During feed stroke, any one pusher detects the high signal of oil pressure in subgroup, then whole subgroup is pushed away
Glassware is wholly off and returns, and restarts from compression stroke.Under non-debugging mode, when occur below any one
Part, pusher function group stop, and all of pusher extreme position stops after returning：1) 32 are taken（It is redundant signals that may I ask？）
Blowing out signal；2) flue gas stops 2 seconds temperature and is less than 850 DEG C（More than 10 minutes）；3) all fire grates stop.
According to Fig. 7, fire grate is divided into level Four from top to bottom, and every grade of fire grate is divided into the left and right sides, totally 8 parts, separates
Control.Rubbish is moved from top to bottom in the action with fire grate, a systematic procedure such as completes to dry, burn, burn.
Each fire grate part can be ceased and desisted order when operator send by the independent start stop operation of operator, and fire grate will be returned
Return to rear extreme position and stop.Operator can also send " fire grate group open/stop order ", while starting or stoping all stoves
Row.
In boiler trip or after stop in 2 seconds, flue-gas temperature≤850 DEG C were limited after all of fire grate return more than 10 minutes
Position simultaneously stops.
In order to the rubbish ensured on fire grate can burn completely and burn, it is necessary to control the thickness of rubbish on fire grate.Per grade
The control of fire grate is relatively independent, and its movement velocity mainly receives burden requirement and fire grate rubbish thickness effect itself.The wherein second level
Fire grate is main burning section, and its speed controlling setting value is directly determined by load setting value；And first order fire grate, third level fire grate are fast
Setting value is spent except being determined by load setting value, also by second level fire grate garbage thickness effect, to ensure that main burning section is maintained
The second level, reaches best burning effect, while being uniformly distributed rubbish, protects fire grate.
Hydraulic Station system is shown in Fig. 3, is provided with two 100% capacity hydraulic oil pumps, there is provided pusher, fire grate, garbage feeding gear
The hydraulic-driven of plate and mucking machine.Hydraulic oil pump outlet is configured with quick-closing valve.When hydraulic oil container liquid level is low, hydraulic oil pump interlocking
Protection stops, while opening fuel pump outlet quick-closing valve.
2 hydraulic oil pumps constitute subgroup, and when any one pump operation, it is standby that operator may be selected input pump group
Lock.During the standby interlocking input of pump group, if working barrel occurs " electric tripping ", a pump is by automatic in addition；If outlet
Pressure is low, and a pump is by automatic in addition.When two pumps all stop or all run, the standby interlocking of pump group is automatically terminated, in case
Only occur circulating between two pumps starting repeatedly.
Hydraulic oil unit cooling oil pump one, after interlocking input, when hydraulic oil temperature is high, automatic prevents hydraulic oil temperature
It is overheated.After hydraulic oil temperature recovers normal, it is automatically stopped.
Hydraulic oil shut-off valve one, in the case of there is boiler trip, protection after time delay 45s is closed, and protects fire grate and pusher
Device can return to home, and protect hydraulic oil unit.
Primary air system is as shown in figure 8, a wind action is drying rubbish, there is provided combustion air, through steam air
First air after preheater heating, sends into incinerator by 8 air inlets from below fire grate.Incinerator has a level Four fire grate, per grade
Fire grate is divided into the left and right sides, one air inlet of correspondence under every section of fire grate.
First air air quantity into every section of fire grate is measured with Deltaflow meter, and First air air measuring value is with " to stove
Air temperature of row " does temperature-compensating calculating.
Main steam flow set point（From DCS boiler loads control centre, the demand of boiler load is represent）, Jing Guohan
Several piece is changed, and produces total combustion air air quantity（That is primary and secondary air total blast volume）Set point.First air, secondary wind ratio can
To be adjusted in certain scope by operator.This part draws First air basis air quantity.
First air variable air quantity is from boiler load control.The control of First air variable air quantity is designed to tandem+feedforward control
Mode processed, it includes main steam flow actuator, at the top of main steam pressure feedforward regulator, and the first flue before flue-gas temperature
Feedback actuator.The scope of First air variable air quantity is ± 21200Nm3/h, in the ideal case the control of First air variable air quantity
Output should be close to zero.
The allocation of the amount of air system that the basic air quantity set point of First air and First air variable air quantity are set according to operator respectively
Number, is prorated to fire grate 1,2,3 and 4.The basic air quantity set point of First air calculated through ratio and the variable wind of First air
The value that amount is added up is used as corresponding fire grate primary air flow set point.By controlling the aperture of 8 First air controllable registers, control respectively
The intake of each section of fire grate of system, to meet demand of the incineration firing to air on each section of fire grate.
Fig. 9, Figure 10 are secondary wind control SAMA figures.Secondary wind action is to set up excessive combustion in secondary gas-phase combustion area
Air is burnt, to guarantee the burning completely of smoke mixture.And, the penetrating of secondary wind can be to form turbulent flow in flue gas, can
Air is made well to mix with flue gas.
Burner hearth face arch is disposed with two row's secondary wind, near the referred to as first row of fire grate（Secondary wind front end 1）, from fire grate slightly away from
For second row（Secondary wind front end 2）, often arranging has 6 spouts.Front-back wall at the first chimney intake of boiler also arranges two-layer
OFA（Over Fire Air）（Secondary wind OFA1, upper strata is secondary wind OFA2 for lower floor）, per layer of 8 spout, front-back wall each 4
Only, the above 28 spouts altogether.
